, endemic to China, is an economically important evergreen tree species and a source of agarwood. Due to the high market demand for agarwood, this species is heavily overexploited in the wild and is now listed as an endangered species. Although its nuclear and chloroplast genomes have been previously reported, little is known about its mitochondrial genome. Using the paired-end short reads generated by the Illumina sequencing platform, we assembled and herein report the mitochondrial genome of . for future phylogenetic, evolutionary, and preservative studies. The length of the . mitochondrial genome was found to be 341,829 bp and the GC content was 45.01%. A total of 32 protein-coding genes, 19 tRNA genes, and three rRNA genes were annotated. The phylogenetic tree indicated that . is most closely genetically related to .
，原产于中国，是一种具有重要经济价值的常绿乔木，也是沉香的来源。由于市场对沉香的高需求，该物种在野外被过度开发，现已被列为濒危物种。尽管其核基因组和叶绿体基因组此前已有报道，但对其线粒体基因组知之甚少。利用Illumina测序平台产生的双末端短读长序列，我们组装并在此报告了的线粒体基因组。用于未来的系统发育、进化和保护研究。发现的线粒体基因组长度为341,829 bp，GC含量为45.01%。共注释了32个蛋白质编码基因、19个tRNA基因和3个rRNA基因。系统发育树表明，与在遗传上关系最为密切。
